我试图从TCP套接字在C#中进行"流式"语音识别.我遇到的问题是SpeechRecognitionEngine.SetInputToAudioStream()似乎需要一个可以寻找的定义长度的Stream.现在,我能想到的唯一方法就是在更多输入进来时在MemoryStream上重复运行识别器.
这里有一些代码来说明:
SpeechRecognitionEngine appRecognizer = new SpeechRecognitionEngine();
System.Speech.AudioFormat.SpeechAudioFormatInfo formatInfo = new System.Speech.AudioFormat.SpeechAudioFormatInfo(8000, System.Speech.AudioFormat.AudioBitsPerSample.Sixteen, System.Speech.AudioFormat.AudioChannel.Mono);
NetworkStream stream = new NetworkStream(socket,true);
appRecognizer.SetInputToAudioStream(stream, formatInfo);
// At the line above a "NotSupportedException" complaining that "This stream does not support seek operations."

有谁知道怎么解决这个问题?它必须支持某种类型的流输入,因为它使用SetInputToDefaultAudioDevice()与麦克风一起工作正常.
谢谢,肖恩
我正在玩这个SAPI v5.1库.所以我正在测试我的样本WAV文件.(从这里下载).无论如何,该文件中的声音清晰简单.它只包含一个单词,即第三个单词.现在,当我运行以下代码时,我得到数字8或"8".如果我删除它,我得到7.如果我尝试随机化列表我得到不同的结果,依此类推.我真的很困惑,开始认为SAPI库中的SpeachRecognition根本不起作用......
无论如何这里是我正在做的,
private void button1_Click(object sender, EventArgs e)
{
//Add choices to grammar.
Choices mychoices = new Choices();
mychoices.Add("one");
mychoices.Add("two");

reco.SetInputToWaveFile("3.wav");
reco.LoadGrammar(myGrammar);
